APP

To all whom it may concern Be it known that l, JOSEPH EDWARD Boss,

a citizen of the United States," residing at- Toronto, in the county of Yorlr'and Province of'Qntario, Canada, have invented certain new and useful Improvements in Apparatus for Making Grain Products, of which the following'is a specification.

This invention relates to apparatus for making food forming products of cereal nature, and has for some of its objects the treatment of grain, such as wheat, rye, corn, barley, oats, riceand other starch bearing cereals, in a manner that constituents of the whole grain are associated with the finished flour and free from the bran or grain coatfore, and it comprises a' cereal food producing product of cellular disrupted nature by which a more thorough digestion of given quantities may be secured in shorter time and with greater nutritive and body building efi'ect and with longer keeping and moisture retaining propertles than the usual grit, meal or flour, whereby less yeast is required to produce greater leavening effect in shorter time and also less su ar and shortening isnecessary in the wor ing up of the product into foods.

In the prior art it has been customary to e grain by the action of water or steam, to a degree that the swellingwill burst the grain cells, then dry, grind, bolt and flour the product, also to reduce the grain to a grit meal or flour, and expose the grit, meal or flourto the action of moistureor its stea'm'variety and then dry and flour or reflour the product, which involves the double handling in the manufactureofthe material, such as grinding, bran separating,

cell disrupting, and regrinding to obtain the.

finished product, and by which means no valuable ingredients of the bran or cell tissue or coating can be introduced into the flour yielded, all of which are obviated in producingthe product of the present invention, which comprises hydrating the gram a 10 on.

' while associated with the bran or grain coating, either as such' or 'inla. rolled or compressed form w1th the natural constituents and bran, by the action of water, preferably of moisture of steam form with or without the augmentation of heat," whereby the starch and 'other ingredients contained in cells aredistended or swelled while retained by or associated with the outer coating of the grain and then directly subjected to the 7 action of direct pressure or compression to such a degree and of such sudden nature that the fluid or water swelled cells are crushed and disrupted for the reason that the water contained therein is unable to pass out through the pores of the cell coatmg or cell coating fibers without disrupting them, and when ruptured effect the introduction into the cell content, such as starch, etc., of the soluble ingredients of the grain epidermis or skin, together with the product produced by the action of water associated with the grain oils under pressure, such as glycerin, which have a preserving and sweetening efi'ect. Then after producing this super-nutritious product, it is dried, ground, bolted and floured.

When the-oil in the grain, associated with water, is subjected to pressure, it becomes dissociated or transformed from its oleic ester character into glycerin and fatty acid, which latter combines with the starchy in;

'gredients present and forms a nutritious product, while the glycerin acts as a moisture retainer and preservative, and the whole results'in a sweeter product than that ordinarily secured.

As an example of a cereal product and process by which it is produced in accordance with the present invention, a product of wheat flour having the character described will be taken as an illustration, reference being directed to the accompanying drawing which diagrammatically illustrates the various steps and means for carrying out the process.

The scraping devices 26 and 57 are of similar form or character of construction and method of operation.

The fiouring member87 is provided with pulleys 96 and 97 foro crating the fiouring rolls at controlled and esired speeds to produce the required results.

As an example of a product and process by which the same is made, the conversion of wheat into the improved product will be taken, reference being directed to the accompanyin drawings illustrating the various steps of the process employed.

The wheat grain is placed in the hopper 10 from which it is supplied through the opening 16 by operating the valve orgate 17. The'wheat grain can be employed directly as such or may be preferably compressed by passing through or between the rollers 23 which are suitably adjusted with relation to each other by means of the adjusting devices 13 to compress the grain to the desired degree of compression. Power is then supplied to the various driving pulleys or gears of the apparatus and the gate valve 17 opened, whereby thegrain as such or in its compressed form passes between the crushing rollers 23 and is deposited upon the traveling belt 18 through the supply duct 15. The grain as such or in its com pressed form is deposited on the traveling belt 18, which is dished by'the angularly disposed' bearings communicating with the outer edges of the upper. belt or conveyer for the purpose ofpreventing the grain from falling off, is carried in a forward progresposited upon the elevating conveyer-or in clined carrier or ,belt 27 situated in the hydrating member, being removed from the belt 18 by the scrapingdevice 26. The inclined carrier or belt 27 is also dished by elevating its edges by means of the angularly disposed rollers 92. As the rain is carried forward .and upward on the inclined belt or 'conveyer27 it is subjected to the action of steam or water vapor supplied above and below the belt through the nozzles or openings 31 and 32 of the conduits 29 and 30, the valves 33 in pi e 29 and 34 in pipe 30 being suitably opene to admit of the discharge of a suficient amount of steam or water vapor to hydrate or swell the grain thereby distending its cells by the action of the internally absorbed water or moisture. This hydrated grain is then discharged into the hopper at the top of chute 36 by the action of the scraper 35. During the hydration of the grain in the hydrating member a current of alr is gradually drawn through in an upward direction by action of the fan or suction device 48, air being admitted through the openings 21 and 46- controlled by the valves or gates 22 and 47 in such a manner and to such a degree that any steam or moisture is carried forward and kept from entering the feed chamber 20.- Any moisture which may condense on the inner member passing through or between the rolls 52 suitably adjusted by the means 53 to thoroughly compress the hydrated grain to a degree that its internal cellular structure is.

ruptured in an attempt of the contained water or moisture to be forced out through the cellular coating at a speed greater than it can normally pass throughthe pores, the rolls being preferably heated by circulation of steam in the interior 54' of the rolls 52. The cell disruptedgrain then falls through the feed means 51 and is deposited upon the traveling belt 56, whereby it is carried through the drying member 64 and subjected to the action of heat communicated through the steam coil 60 controlled by valves 61 and 62. At the same time the heating and drying of the grain is being accomplished a current of air is drawn through the drier by means of the exhaust device 69, the volume of air being controlled by the regulating valve or damper 68 which operates to regu-- late'the area of the air supply 0 ening 67. As the grain is dried and carried ortvard on the belt or carrier 56 and reaches its farther end, it is removed by the scraper 59 and deposited into the chute 63 from which it is supplied to the scraping or grinding member 74 provided with the disintegrating rolls 71 suitably heated or cooled as the case integrated grain passes out through the outlet 7 5 through the flexible conduit 76 into the bolting members 7 8 and 79 where the bran depleted of its soluble ingredients,

The woody fiber constituting the cell wall is disrupted, delivering 01: freeing the starchy contents,

which is also associated with gl cerin and tionof the fatty acids, liberated bythe ac-- tion of pressure and moisture in contact with the starchy ingredients.- This product diflers from products of the prior art, which are made after separating the branthe additional health giving and nutriment delivering constituentsof the whole grain derived from both the bran and thecell nucleus or germ;

constructed may be of any kind or character and the construction may be of any arrangement or form other than that shown and described so long as-; the integrity of the members and their 'coaction in operation are sired result may be obtained without departlng from the spirit of the invention.

The conveyor member, such as the" contin-- uous belt shown, for carryin the' g'rain may form, or of other materialor of other charac ter ofstructure or form of construction, or it may comprise other mechanism or device, suchas rotary or rotatable convey f orcan;
